The longcase clock (also known as the grandfather clock) was created to house the pendulum and works by the English clockmaker William Clement in 1670 or 1671. It was also at this time that clock cases began to be made of wood and clock faces to use enamel as well as hand-painted ceramics. In 1670, William Clement created the anchor escapement ...
Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time is a 1995 best-selling book by Dava Sobel about John Harrison, an 18th-century clockmaker who created the first clock (chronometer) sufficiently accurate to be used to determine longitude at sea—an important development in navigation.
The invention of the verge and foliot escapement in c.1275 [87] was one of the most important inventions in both the history of the clock [88] and the history of technology. [89] It was the first type of regulator in horology. [6] A verge, or vertical shaft, is forced to rotate by a weight-driven crown wheel, but is stopped from rotating freely ...
These two types are made by the International Time Recording Co. of New York. [13] An example of this other form of time clock, made by IBM, is pictured. The face shows employee numbers which would be dialed up by employees entering and leaving the factory. The day and time of entry and exit was punched onto cards inside the box. [14]
Eli Terry Sr. (April 13, 1772 – February 24, 1852) was an inventor and clockmaker in Connecticut.He received a United States patent for a shelf clock mechanism. He introduced mass production to the art of clockmaking, which made clocks affordable for the average American citizen.
In 1818 he invented and patented a type of mantel clock, known as the lighthouse clock and regarded as the first alarm clock produced in America. [6] Originally known as the "Patent Alarm Timepiece", they have become known as lighthouse clocks (a 20th-century term) for their obvious similarities.
Galileo's escapement is a design for a clock escapement, invented around 1637 by Italian scientist Galileo Galilei (1564–1642). Galileo was one of the leading minds of the Scientific Revolution. [1] He was dubbed the founder of theoretical physics. [2]
The mainspring, invented in the 15th century, allowed small clocks to be built. Leonardo da Vinci produced the earliest drawings of a pendulum while the pendulum clock, designed by Christiaan Huygens in 1656, was more accurate than other mechanical timekeepers. The electric clock, invented in 1840, controlled the most accurate pendulum clocks ...
